All hydrogenous sediments are formed from the precipitation of minerals directly from seawater. They typically consist of chemical compounds that crystallize out as a result of changes in water chemistry, temperature, or biological activity. Common examples include manganese nodules, phosphorites, and carbonates. These sediments often accumulate in specific marine environments, reflecting the local geochemical conditions.
Hydrogenous sediments form when minerals precipitate directly from seawater as a result of chemical reactions or biological processes. For example, manganese nodules and phosphorite deposits are examples of hydrogenous sediments that form in this way in the deep sea. These sediments accumulate slowly over time on the ocean floor.
Marine sediments are typically classified into four main classes: terrigenous, biogenous, hydrogenous, and cosmogenous. Terrigenous sediments originate from land, consisting of eroded rocks and soil transported by rivers and wind. Biogenous sediments are derived from biological materials, primarily the remains of marine organisms like foraminifera and diatoms. Hydrogenous sediments form directly from the precipitation of minerals from seawater, while cosmogenous sediments come from extraterrestrial sources, such as meteorites.

Common sediments produced by glaciers include till (unsorted mixture of rocks and sediment), moraine (deposits of till), outwash (sorted sediments deposited by meltwater), and glacial erratics (large boulders transported by glaciers from distant locations).
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
Hydrogenous sediments are formed when minerals precipitate from the ocean, or they can be formed when minerals in the water react with older sediments.

The three types of ocean floor sediments are terrigenous, biogenous, and hydrogenous. Terrigenous sediments are derived from land and consist of particles from weathered rocks, while biogenous sediments are formed from the remains of marine organisms, such as shells and skeletons. Hydrogenous sediments precipitate directly from seawater and include minerals like manganese nodules. These sediments play a crucial role in the oceanic ecosystem and the geological processes of the ocean floor.
Ocean floor sediments primarily consist of three types: terrigenous, biogenous, and hydrogenous sediments. Terrigenous sediments originate from land, including clays and silts brought by rivers and wind. Biogenous sediments are formed from the remains of marine organisms, such as foraminifera and diatoms, while hydrogenous sediments precipitate directly from seawater, including minerals like manganese nodules. Additionally, cosmogenous sediments, derived from extraterrestrial sources like meteorites, are also present but in smaller amounts.

not a hydrogenous sediment?
The three types of ocean floor sediments are terrigenous (derived from land sources), biogenous (derived from biological organisms), and hydrogenous (derived from chemical processes in seawater).
Undisturbed seafloor sediments will carry a history of what has transpired there, much like glacial ice or peat bogs. Some interesting and potentially valuable mineral deposits are also found on the seafloor, eg. manganese nodules, metals from black smokers, and of course, deep in the rock, oil.
Manganese nodules are polymetallic concretions found on the ocean floor and are formed through a slow process of precipitation and accumulation of manganese and other metals. They are a type of sediment known as hydrogenous sediment, as they form directly from seawater and not from the breakdown of rocks or organic materials.
